An oligopsony is a type of market structure characterized by the presence of a limited number of large buyers who dominate the purchase of products or services from a larger number of suppliers. This contrasts with a monopoly, which is dominated by a single seller, or an oligopoly, dominated by a few sellers.
In the case of an oligopsony, these few buyers have significant market power and can influence prices, terms of purchase, and even the quality of products delivered by sellers.
A notable example of an oligopsony is the tobacco industry, where approximately five major companies purchase tobacco leaves from many growers.
Characteristics of Oligopsony
The primary characteristics of an oligopsony include:
- Few Buyers: Only a small number of buyers exist in the market.
- Market Power: These buyers have significant control over the market conditions and prices.
- Price Influence: Buyers can dictate the prices due to their substantial control.
- Barriers to Entry: High barriers can exist for new buyers due to the dominance of the few.
Economic Representation
In economic terms, the pricing in an oligopsony can be influenced by the marginal cost and average cost, which can be represented as:
Where \( P \) is the price set by the buyers, \( MC \) is the marginal cost, and the Market Influence Factor is the additional control exerted by the few buyers.
Examples of Oligopsony Markets
- Tobacco Industry: Companies like Altria, British American Tobacco, and Philip Morris dominate the purchase from numerous tobacco farmers.
- Defense Industry: Governments act as major buyers of military equipment from a few manufacturers.
- Retail Sector: Large retail chains like Walmart control the purchasing power from various suppliers.
Case Study: Tobacco Industry
In the tobacco industry:
- Few major buyers (tobacco companies) have significant control over pricing.
- Numerous small growers depend on these few companies for their livelihood.
- This can lead to lower prices for growers as they have limited alternative buyers.
Historical Context
Historically, oligopsonies have played crucial roles in various industries, evolving from situations where production scales increased and few companies emerged as dominant players. The evolution of oligopsony markets is often tied to industrial revolutions and technological advances, creating high entry barriers for new buyers due to the substantial capital required.
Applicability and Impact
Economic Efficiency
While oligopsonies can create efficiencies in procurement and logistics, they may also lead to unfair pricing for suppliers. For instance, in agricultural sectors, farmers may receive lower prices due to lack of competition among buyers.
Regulatory Considerations
Governments may regulate oligopsonies to ensure fair competition and prevent market abuse. Antitrust laws and competition regulations are designed to prevent dominant buyers from abusing their market position.

Summary
Oligopsonies represent a unique market structure wherein a few dominant buyers control the purchase dynamics significantly, impacting pricing, competition, and market fairness. Understanding this concept helps in appreciating the complexities of industrial economics and the necessity of regulations to maintain market balance.
